The next six months
Odds of each outcome compared with the 1993–2016 average.
December–February
February–April
In the tropics, seasonal forecasts generally have useful skill during strong El Niño years, but they give odds, not certainties. “Normal” is the middle third of the model's own 1993–2016 range. Because the climate has warmed since then, “warmer” is the usual result almost everywhere.

What Bangladesh emits, and how it makes electricity
Bangladesh emitted 115.9 million tonnes of carbon dioxide from fossil fuels and industry in 2025, 0.30% of the world total, or 0.7 tonnes per person. That is up 709% since 1990.

What you can do
If it turns out wetter
- Find out whether your home, school or workplace is in a flood-risk area, and know your evacuation route.
- Clear gutters and drains before the rainy months.
- Keep important documents, medicines and a torch in a waterproof bag.
- After heavy rain, avoid walking or driving through flood water and follow local advice on drinking water and mosquito-borne disease.
If it turns out hotter
- Check on older relatives, neighbours and anyone who lives alone during hot spells.
- Drink water regularly, and avoid hard outdoor work in the hottest hours.
- Know the signs of heat exhaustion (dizziness, headache, nausea) and when to get medical help.
On smoky or hazy days
- Check the daily air-quality forecast and cut down hard outdoor exercise when it is 'Unhealthy' or worse.
- A well-fitted N95 or KN95 mask reduces smoke exposure; cloth and surgical masks do much less.
- Keep windows closed and use an air purifier with a HEPA filter if you have one.
- People with asthma, heart or lung disease, older people, children and pregnant people should take extra care.
